“Parallel coordinate visualizations have a reputation of being difficult to understand, expert-only representations. We argue that this reputation may be partially unfounded, because many of the parallel coordinate browser implementations lack essential features. This paper presents a survey of current interaction techniques for parallel coordinate browsers and compares them to the visualization design guidelines in the literature. In addition, we report our experiences with parallel coordinate browser prototypes, and describe an experiment where we studied the immediate usability of parallel coordinate visualizations. In the experiment, 16 database professionals performed a set of tasks both with the SQL query language and a parallel coordinate browser. The results show that although the subjects had doubts about the general usefulness of the parallel coordinate technique, they could perform the tasks more efficiently with a parallel coordinate browser than with their familiar query language interface.”

Jhaveri, Natalie and Raiha, Kari-Jouko (2005): The advantages of a cross-session web workspace. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 1949-1952.
“Conducting research using the web is often an iterative process of collecting, comparing and contrasting information. Not surprisingly, web-based research tasks habitually span multiple web sessions and involve considerable web page revisitation. Such tasks are not only carried out by researchers, but also by casual web users who, for example, plan vacations and large purchases. Despite the prominence of this activity among web users, existing tools support it poorly. We propose an alternative approach, whereby web-based research tasks are facilitated by a web workspace which represents collected URLs with web page thumbnails. A prototype of our design was developed and studied in an evaluation with 12 participants. Each of the participants adopted the workspace approach instinctively: the workspace was used for web page revisitation, web page comparison, collection overview, cross-session task continuation, and continuous task focus.”

“Speech-based applications commonly come with web-based or printed manuals. Alternatively, the dialogue can be designed so that users should be able to start using the application on their own. We studied an alternative approach, an integrated tutor. The tutor participates in the interaction when new users learn to use a speech-based system. It teaches the users how to operate the system and monitors user actions to be certain that the users do indeed learn. In this paper we describe our experiences with the design and the iterative development of an integrated tutor. Expert evaluation and two user tests were conducted with different versions of the tutor. The results show that the tutor can effectively guide new users. We identify the six most important lessons learned, the most important being that it is essential to spot problems by monitoring user actions, especially when novice users are tutored.”

Raisamo, Roope and Raiha, Kari-Jouko (2000): Design and Evaluation of the Alignment Stick. In Interacting with Computers, 12 (5) pp. 483-506.
“Object alignment is one of the basic operations in drawing programs. Current solutions provide mainly three ways for carrying out this operation: either by issuing an alignment command, or by using direct positioning with the help of gravity active points, or by making use of constraints. The first technique has limited functionality, and the other two may be difficult to learn for a novice. We describe here a new direct manipulation tool for alignment. We show that while direct manipulation helps to make the normal use of the tool intuitive, it also offers advanced functionality not found in current commercial products. We report on an empirical study in which we compared the ease of use, intuitiveness, learnability, and efficiency of alignment menus, palettes and the alignment stick. In the study novice users found the basic operation of the alignment stick natural and easy to learn. The increased functionality was best appreciated and utilized by the experienced users.”

Aaltonen, Antti, Hyrskykari, Aulikki and Raiha, Kari-Jouko (1998): 101 Spots, or How do Users Read Menus?. In: Karat, Clare-Marie, Lund, Arnold, Coutaz, Joëlle and Karat, John (eds.) Proceedings of the ACM CHI 98 Human Factors in Computing Systems Conference April 18-23, 1998, Los Angeles, California. pp. 132-139.
“In modern graphical user interfaces pull-down menus are one of the most frequently used components. But still after years of research there is no clear evidence on how the users carry out the visual search process in pull-down menus. Several models have been proposed for predicting selection times. However, most observations are based only on execution times and cannot therefore explain where the time is spent. The few models that are based on eye movement research are conflicting. In this study we present an experiment where eye movement data was gathered in a menu usage task. By analyzing the scan paths of the eye, we found that menus are read in sequential sweeps. This may explain why the best models produced by previous research are hybrid models that combine systematic reading behavior with random reading behavior.”

Proceedings of the 9th annual ACM symposium on User interface software and technology November 06 - 08, 1996, Seattle, Washington, United States. pp. 157-164.

The first technique has limited functionality, and the other two may be mysterious for a novice. We describe here a new direct manipulation tool for alignment. We show that while direct manipulation helps to make the tool intuitive, it has through iterative design evolved into a tool that also offers functionality not found in current commercial products.”
